.TP 
.BR "\-O net_buffer_length=#, where # < 16M "
When creating multi-row-insert statements (as with option 
.BR --extended-insert 
or 
.BR --opt
), mysqldump will create rows up to net_buffer_length length. If you increase this variable, you should also ensure that the max_allowed_packet variable in the MySQL server is bigger than the net_buffer_length. 
.SH EXAMPLES
.TP
The most normal use of mysqldump is probably for making a backup of whole
databases. See the section on Database Backups in the MySQL Reference Manual. 
.TP
mysqldump  \-\-opt \fP\fIdatabase\fP > backup-file.sql
.TP
You can read this back into MySQL with: 
.TP
.BR mysql 
\fP\fIdatabase\fP 
.BR < 
backup-file.sql
.TP
or 
.TP
.BR mysql 
\-e 'source /patch\-to\-backup/backup\-file.sql' database
.TP
However, it's also very useful to populate another MySQL server with information from a database: 
.TP
mysqldump \-\-opt \fP\fIdatabase\fP | mysql \-\-host=\fP\fIremote\-host\fP \-C database
.TP
It is possible to dump several databases with one command: 
.TP
mysqldump \-\-databases database1 [ database2 database3... ]  > my_databases.sql
.TP
If all the databases are wanted, one can use: 
.TP
mysqldump \fP\fI\-\-all\-databases\fP > all_databases.sql
